Qwythos-9B-Claude-Mythos-5 Released with 1M Token Context Window
Qwythos-9B-Claude-Mythos-5 has been released with a context window of up to 1 million tokens.
The Empero team introduced its reasoning model Qwythos-9B, built on a deeply uncensored version of Qwen3.5-9B. The model received a full fine-tune of all parameters and was additionally trained on more than 500 million tokens of Claude Mythos and Claude Fable data.
Synthetic Chain of Thought (CoT) generated from Fable-5 and Mythos-5 session logs was used for training.
